Job Title: HWIL SW Integration Engineer Sr (E3) | Orlando, FL | 10669

Posting Start Date: 10/8/26

Standard Job Description

The HWIL Software Integration Engineer (E3) provides technical support for the development, integration, and verification of real‑time, closed‑loop Hardware‑in‑the‑Loop (HWIL) simulations that combine missile hardware components with high‑performance software models. With 3+ years of relevant experience, the incumbent works under senior guidance, contributes to integration strategies, and represents Lockheed Martin to government and industry partners on technical matters.

Core Responsibilities

• Software Architecture & Strategy
  • Assist in defining and maintaining the software architecture for HWIL test‑beds.
  • Support standards for real‑time code, low‑latency data paths, and deterministic execution.
• Missile Software & Model Integration
  • Contribute to the integration of missile flight software, guidance algorithms, and sensor models into closed‑loop simulation environments (including 6‑DOF dynamics).
• Real‑Time Integration & Timing
  • Help ensure latency and timing budgets are met for hardware‑to‑software interfaces by performing time‑domain analysis and jitter budgeting.
  • Implement and verify synchronization mechanisms between missile hardware (actuators, sensors, RF targets) and simulation models on RTOS or FPGA/HPC platforms.
• Integration & Verification
  • Participate in software‑hardware integration activities, debugging interface protocols, timing mismatches, and data‑integrity issues.
  • Contribute to verification and validation (V&V) plans, traceability matrices, and validation reports.
• Hardware Interaction & Test Equipment
  • Apply hands‑on hardware skills (RF testing, cable harness checks, target generation) to support software integration.
  • Operate test equipment such as oscilloscopes, spectrum/network analyzers, RF signal generators, and high‑speed data acquisition systems.

Basic Qualifications

• Experience: 3+ years in software development, real‑time integration, and HWIL environments; demonstrated ability to integrate missile hardware with real‑time simulations.
• Education/Training: Bachelor’s degree in Computer Engineering, Software Engineering, Computer Science, or related STEM field (Master’s preferred).
• Clearance: Active Secret clearance (interim required at start).
• Technical Expertise:
  • Proficiency in C/C++ and real‑time operating systems (e.g., RedHawk, VxWorks, RTLinux).
  • Understanding of low‑latency communication protocols (e.g., Ethernet/IP, MIL‑STD‑1553, CAN).
  • Working knowledge of RF testing, target generation equipment, and missile hardware interfaces.
  • Hands‑on experience with lab equipment (oscilloscope, spectrum analyzer, network analyzer).
• Leadership & Communication: Ability to work effectively within multidisciplinary teams, communicate technical concepts clearly, and produce quality documentation.

Desired Skills

• Experience supporting HWIL software integration for missile or aerospace programs, including latency budgeting and timing verification.
• Familiarity with model‑based development environments and code generation for real‑time execution.
• Knowledge of industry standards and best practices for HWIL real‑time simulation design.
• Experience interacting with government customers for test support and issue resolution.
